[vtkusers] vtkImageData from pixel data

[Suganthi]

Hello vtkUsers,


We are trying to obtain the vtkImageData from the byte* (24bit pixel data).
When we create a bmp file we get crash in writing a BMPFile in the method
"void vtkBMPWriter::WriteFile(ofstream *file, vtkImageData *data,int
extent[6]) "


kindly tell us what is wrong with this code,  And we want to know what are
the header parameters to be set for the vtkImageData.


void CMainFrame::ImageData(byte* src)
{

	vtkImageData *outData = vtkImageData::New();

	byte arry[320*240*3];
	memcpy(arry,src,320*240*3);

	vtkImageImport *import = vtkImageImport::New();
	import->SetDataExtent(0,319,0,239,0,0);
	import->SetWholeExtent(0,319,0,239,0,0);
	import->SetDataScalarType(VTK_UNSIGNED_CHAR);
	import->SetImportVoidPointer((void*)src);
	import->UpdateWholeExtent();


	outData = import->GetOutput();

	outData->SetNumberOfScalarComponents( 1 );


	int iNo = outData->GetNumberOfScalarComponents();
	WriteBMP(outData);


	return;

}


void Definitions::WriteBMP(vtkImageData *source)
{
	vtkBMPWriter write =vtkBMPWriter::New();
	 write->SetFilePrefix("C:/tested/tested");
     	 write->SetFilePattern("%s%d.bmp");
	 write->SetInput(source);
	 write->Write();
}

regards
SoftUsers
